3.2.4 Leveling

Place a level bar in vertical direction on the top-plane of the lower support to check

the levelness of the lower support. When errors occur, adjust the levelness by adding

washers beneath the lower support as shown in Figure 3-6.

Set the multi-meter at the resistance measurement position. Cont act the cabinet and

expansion bolts respectively with the two measuring probes of the multi-meter to

measure the resistance. If the circuit is disconnected, complete the installation.

Otherwise, it indicates that the cabinet is not insulated. In this case, check whether

any insulating covering or insulating washer is missing, or whether any insulating

covering is damaged. Repeat the installation of the lower support and perform the

insulation test again.
